Description

Forbindelse for møbelunderstell av stålrør. Connection for furniture bases made of steel pipes.

Oppfinnelsen angår et møbelyn^dersteli, særlig bordunderstell, omfattende et eller flere rette stålrørstykker med rektangulært eller kvadratisk tverrsnitt, hvortil et iverrgående stålrør-stykke med tilsvarende tverrsnitt er festet ved hjelp av løsbare monteringsorganer. The invention relates to a furniture frame, in particular a table base, comprising one or more straight steel pipe pieces with a rectangular or square cross-section, to which a protruding steel pipe piece with a corresponding cross-section is attached by means of detachable mounting means.

Av hensyn til lagring og forsendelse er det ofte ønskelig at møbelunderstell av stålrør kan adskilles, rørene forenes derfor visse steder ved hjelp av løsbare monteringsorganer, såsom skruer eller bolter, i stedet for ved sveising. De kjente monteringsorganer vil imidlertid ikke kunne gi den nødvendige stivhet, hvilket i alminnelighet er et uomgjengelig krav til et møbelunderstell, særlig et bordunderstell som skal være så stabilt som mulig. En sådan stivhet kan ikke oppnås ved hjelp av de gjengse boltforbindelser. For reasons of storage and shipping, it is often desirable that furniture bases made of steel tubes can be separated, the tubes are therefore joined in certain places by means of detachable mounting devices, such as screws or bolts, instead of by welding. However, the known mounting means will not be able to provide the required rigidity, which is generally an unavoidable requirement for a furniture base, in particular a table base which must be as stable as possible. Such rigidity cannot be achieved using the usual bolted connections.

Formålet med oppfinnelsen er å skaffe et understell av den omhandlede art, som er forsynt med lett adskillbare monteringsorganer som kan gi understellet den nødvendige stivhet og stabilitet. The purpose of the invention is to provide a chassis of the type in question, which is provided with easily separable mounting elements which can give the chassis the necessary rigidity and stability.

Det særegne ved understellet ifølge oppfinnelsen er at det ene rørstykke har en således utformet utskjæring at der dannes to vinkelrett på hinannen stående anleggsflater, mot hvilke to sideflater på det annet i utskjæringen anbragte rørstykke ligger an, og at der i dette rørstykke finnes to ovenpå hinannen anbragte spénn-stykker som har trykkflater som er parallelle med anleggsflåtene mens spennstykkenes mot hinannen liggende flater er skrå i forhold til anleggsflåtene og en spennbolt er ført gjennom spennstykkene og er skrudd inn i et derunder anbragt organ.. The peculiarity of the undercarriage according to the invention is that one piece of pipe has a cut-out designed in such a way that two contact surfaces standing perpendicular to each other are formed, against which two side surfaces of the other piece of pipe placed in the cut-out rest, and that in this piece of pipe there are two on top of each other placed clamping pieces which have pressure surfaces that are parallel to the construction rafts, while the facing surfaces of the clamping pieces are inclined in relation to the construction rafts and a tension bolt is passed through the clamping pieces and is screwed into a body placed underneath..

Ved hjelp av disse forholdsvis enkle midler kan der på det sted, hvor to rør krysser hinannen, foretas en sammenspenning i to vinkelrett på hinannen stående retninger, således at.to sett anleggsflater samtidig spennes mot hinannen, hvilket gir en.meget stiv forbindelse. With the help of these relatively simple means, at the point where two pipes cross each other, a tension can be made in two directions perpendicular to each other, so that two sets of contact surfaces are simultaneously tensioned against each other, which gives a very rigid connection.

Ved en særlig hensiktsmessig utførelse av et møbelunder-stell ifølge oppfinnelsen er anleggsflåtene på det første rør dannet ved en vinkelutskjæring i rørets ende, således at den ene anleggsflate er parallell med rørets lengderetning og den annen er vinkelrett på samme, mens anleggsflåtene på det annet rør består av to av dettes vinkelrett på hinannen stående sideflater, idet spennbolten er innskrudd i en mutter som er festet i det første rør under den parallelt med rørets lengderetning forløpende anleggsflate, og spennstykkene er anbragt inne i det annet rør. In a particularly suitable embodiment of a furniture base according to the invention, the contact surfaces on the first pipe are formed by an angled cutout at the end of the pipe, so that one contact surface is parallel to the longitudinal direction of the pipe and the other is perpendicular to it, while the contact surfaces on the second pipe consists of two of its side surfaces standing perpendicular to each other, the clamping bolt being screwed into a nut which is fixed in the first pipe under the contact surface running parallel to the pipe's longitudinal direction, and the clamping pieces are placed inside the second pipe.

Denne utførelse har for det førsre den fordel at spennorganene befinner seg inne i det ene rørs hulrom og således ikke bry-ter understellets glatte overflater, og for det annet den fordel at der oppnås en særlig stiv forbindelse, idet det rør, i hvilket spennorganene befinner seg, spennes dels mellom den i det annet rør fes-tede mutter og et av spennstykkene og dels mellom det annet spennstykke og tre endekanter på det rør som bærer mutteren, således at ettergivenheten i forbindelsesdelene blir meget liten. This design has, firstly, the advantage that the tensioning members are located inside the cavity of one tube and thus does not break the smooth surfaces of the undercarriage, and secondly the advantage that a particularly rigid connection is achieved, as the tube in which the tensioning members are located itself, is clamped partly between the nut attached to the other pipe and one of the clamping pieces and partly between the other clamping piece and three end edges of the pipe carrying the nut, so that the compliance in the connecting parts is very small.

I det følgende skal beskrives et utførelseseksempel på et møbelunderstell ifølge oppfinnelsen under henvisning til tegningen, på hvilken fig. 1 viser i perspektiv en del av understellet med to ikke monterte stålrør som krysser hinannen, fig. 2 viser et snitt av de to stålrør med monteringsorganer og fig. 3 viser monteringsorganene sett i perspektiv. In the following, an embodiment of a furniture base according to the invention will be described with reference to the drawing, in which fig. 1 shows a perspective view of part of the undercarriage with two unmounted steel tubes crossing each other, fig. 2 shows a section of the two steel pipes with mounting elements and fig. 3 shows the mounting members seen in perspective.

Fig. 1 viser et første stålrør 1 med rektangulært tverrsnitt og en utskjæring 2 i en av sideflatene samt et sirkulært hull 3 i den motstående sideflate. Sistnevnte sideflate er antydet med en skravert firkant, som er betegnet med 4, og en derpå vinkelrett på denne stående sideflate 5. De utvendige overflater av disse to sideflater danner anleggsflater for sammenspenningen, som beskrevet i det følgende. Fig. 1 shows a first steel pipe 1 with a rectangular cross-section and a cut-out 2 in one of the side surfaces as well as a circular hole 3 in the opposite side surface. The latter side surface is indicated by a hatched square, which is denoted by 4, and one perpendicular to this vertical side surface 5. The outer surfaces of these two side surfaces form contact surfaces for the clamping, as described below.

Et annet stålrør 6 som likeledes har rektangulært tverrsnitt, er forsynt med et vinkelformet utsnitt 7 i den ene ende for å danne to vinkelrett på hinannen stående anleggsflater 8 og 9 som likeledes er antydet ved skraverte firkanter. Den førstnevnte an-leggsf late 8 er dannet av to rørkanter 10 og 11 og en mellom disse fastsveiset mutter 12 med gjenger 13. Den annen anleggsfalte 9 er dannet av tre i et felles plan liggende rørkanter 14, 15 og 16. Another steel pipe 6, which likewise has a rectangular cross-section, is provided with an angled cut-out 7 at one end to form two contact surfaces 8 and 9 standing perpendicular to each other, which are also indicated by hatched squares. The first-mentioned mounting surface 8 is formed by two pipe edges 10 and 11 and a nut 12 with threads 13 welded between them. The second mounting surface 9 is formed by three pipe edges 14, 15 and 16 lying in a common plane.

Monteringsorganene ifølge fig. 3 består av en skrue 17 og to spennstykker 18 og 19 som har to mot hinannen liggende skråflater 20 antydet ved skraverte firkanter, og to vinkelrett på hinannen stående spennflater 21 og 22. bet øvre spennstykke 18 har et gjennomgående hull 23 med avlangt tverrsnitt og det nedre spennstykke 19 et gjennomgående hull 24 med sirkulært tverrsnitt. The assembly members according to fig. 3 consists of a screw 17 and two clamping pieces 18 and 19 which have two inclined surfaces 20 lying opposite each other indicated by hatched squares, and two clamping surfaces 21 and 22 standing perpendicular to each other. The upper clamping piece 18 has a through hole 23 with an elongated cross-section and the lower clamping piece 19 a through hole 24 with a circular cross-section.

Ved montering av rørene legges røret 1 inn i vinkelutskjæ-ringen 7 med anleggsflaten 5 liggende an mot anleggsflaten 9 og an-leggsf laten 4 liggende an mot anleggsflaten 8. Deretter anbringes, som vist på fig. 2, spennstykkene i rørets 1 hulrom, dvs. spennstyk-kets 19 anleggsflate 22 anbringes på bunnen av røret 1, mens spennstykket 18 anbringes ovenpå spennstykket 19 med anleggsflaten 21 vendende mot anleggsflaten 9. Spennstykket 18 er noe lengre enn bredden av røret 6, således at det kan ligge an mot kantene 14 og 16. Skruen 17 føres gjennom hullene 23 og 24 og skrus inn i gjenge-hullet 13, hvorved for det første spennstykket 19 spennes mot rørets 1 nedre side som presses mot anleggsflaten 8, og for det annet spennstykket 18 og røret 1 som følge av skråflatene 20 presses til høyre, fig. 2, da spennstykket 19 fastlåses, idet bolten 17 ligger an i det sirkulære hull 24, hvorved anleggsflaten 21 presses mot an-leggsf laten 9, dvs. mot kantene 14, 15 og 16. When installing the pipes, the pipe 1 is inserted into the angle cut-out 7 with the contact surface 5 lying against the contact surface 9 and the contact surface 4 lying against the contact surface 8. Then, as shown in fig. 2, the clamping pieces in the cavity of the pipe 1, i.e. the contact surface 22 of the clamping piece 19 is placed on the bottom of the pipe 1, while the clamping piece 18 is placed on top of the clamping piece 19 with the contact surface 21 facing the contact surface 9. The clamping piece 18 is somewhat longer than the width of the pipe 6, thus that it can rest against the edges 14 and 16. The screw 17 is passed through the holes 23 and 24 and screwed into the threaded hole 13, whereby firstly the clamping piece 19 is clamped against the lower side of the pipe 1 which is pressed against the contact surface 8, and secondly the clamping piece 18 and the pipe 1 as a result of the inclined surfaces 20 are pressed to the right, fig. 2, when the clamping piece 19 is locked, as the bolt 17 rests in the circular hole 24, whereby the contact surface 21 is pressed against the contact surface 9, i.e. against the edges 14, 15 and 16.

Derved tilveiebringes der ved hjelp av en enkelt skrue en fullstendig stiv forbindelse mellom de to rør 1 og 6, således at det møbelunderstell, eventuelt bordunderstell, som har en eller flere forbindelser av den beskrevne art, vil bli tilfredsstillende stabilt. Thereby, a completely rigid connection between the two pipes 1 and 6 is provided by means of a single screw, so that the furniture base, possibly table base, which has one or more connections of the described kind, will be satisfactorily stable.

Monteringen, er skjult, idet spennorganene befinner seg i rørenes hulrom, og understellet vil derfor få et glatt og tiltalen-de ytre. Det kan ved hjelp av forholdsvis få forbindelser av den anførte art lett skilles ad i seksjoner som har en for lagring og forsendelse hensiktsmessig form. The assembly is hidden, as the tensioning devices are located in the cavity of the pipes, and the undercarriage will therefore have a smooth and appealing exterior. With the help of relatively few connections of the type mentioned, it can be easily separated into sections that have a suitable shape for storage and shipping.
